9 Claims.

The invention pertains to small metallic jars of the type especiallyAsuited for use as a container for cold cream, ointments and the like,and usually made of glass or similar materials.

The primary object of the invention is to provide a jar or container ofthe character indicated, which is constructed of sheet metal, and whichcombines the advantages of lightness in weight and attractiveness inappearance with a novel and advantageous construction, such that theinterior surface is entirely free from joints or crevices and an outersurface devoid of sharp or raw edges.

A further object is to provide a metallic jar or container of thecharacter indicated, which is of advantageous construction such that alow cost of manufacture is attained.

The objects of the invention thus generally stated together with otherand ancillary advantages, are attained by the construction andarrangement illustrated in the accompanying drawing forming part hereof,wherein:

Figure 1 is a perspective view of my improved jar or'container.

Fig. 2 is a central vertical sectional View through the container.

Fig. 3 is a similar view showing a modified construction.

In carrying out my invention, I employ a double walled construction forthe container comprising inner and outer shells spaced apart to form anarrow annular air space between them and having their upper endportions coacting to forma neck of reduced diameter adapted to receivethe skirt of a closure cap,l and to provide an entirely smooth innersurface and an outer surface lending itself to attractive decoration andavoiding exposed sharp or rough edges. y Referring now to Figs. 1 and 2of the drawing, a preferred embodiment of the invention comprises spacedouter and inner shells 'I and 8 with their upper end portions coactingto form a neck 9 of reduced external diameter. The container is closedby a cap or cover I0 having a depending skirt II fitting over the neck9.

The outer shell 1 is made from flat sheet metal of relatively lightgauge and comprises a vertical peripheral side wall I2 preferablycylindrical in form. A flat bottom wall I3 in the form of a disk litssnugly within the lower end portion of the peripheral side wall andrests upon the upper edge of an inwardly and upwardly curled flange I4.

The inner shell 8 is preferably drawn from a at sheet of metal toprovide a peripheral side (Cl. 22o-10) wall I5 and a bottom wall I5. Asherein shown, the bottom wall I5a of the inner shell rests upon thebottom wall I3 of the outer shell although it will be apparent that thelatter wall may, if desired, be dispensed with in which event the innershell may engage directly with the ange I4 of the outer shell.

A feature of primary importance in the provision of a container forreceiving cold creams, ointments and the like is the constructionemployed in forming the neck 9. This construction` comprises in thepresent instance a reduced upper end portion I6 on the outer peripheralside wall I2, and a flange I1 formed at the upper end of the inner sidewall I5. The latter abuts the extreme upper edge of the reduced portionI6 and is thence folded downwardly thereover to form a smooth andrelatively wide collar IIa for the neck and at the same time serving tounite the two shells in an interlocking seam.

In forming the reduced upper end portion I6 of the outer shell, anupwardly facing shoulder I8 of substantial radial width is formed, andthe ange I1 is made of a width such that the free edge of the collar IIaformed thereby abuts 2'5 the shoulder I8. Thus the shoulder effectuallycovers the lower free edge of the collar I'Iab thereby serving toprevent injury to the hand of the user.

Outwardly of the collar Ile the shoulder I8, because of its substantialwidth, opposes the lower end of the cap skirt II which may thus bedisposed substantially in the plane of the outer side wall I2.Preferably, the lower edge of the skirt II is curled as indicated at I9so as to conceal the sharp edge of the metal. Also, as will be evident,this curled edge of the skirt forms a projecting bead facilitating theremoval of the cover.

By the construction thus employed, the two shells are firmly securedtogether, the interior of the container is of substantially uniformdiameter from top to bottom, and the inner surface entirely devoid ofseams, crevices, joints or rough edges, while the upper end of thecontainer ter- 40 minates in a smooth rounded edge. Externally of thecontainer, sharp or rough edges are effectually concealed, and when thecap or cover is in position the container is of substantially uniformdiameter from top to bottom with the exception of the bead I9. Finally,a narrow insulating dead air space 20 is formed between the two shellswhich space is closed at its upper end by the shoulder I3 and at itslower end by the bottom wall I3 of the outer shell.

The cap l0 may be made from a flat sheet of metal drawn to provide thedepending skirt H. Preferably, the top of the cap is formed with aslight upward bulge, and within the cap is tted a fiat liner 2|engageable near its peripheral edge with the upper rounded edge of theneck 9. Due to the bulge in the top wall of the cap, an insulating deadair space 22 is formed within the cap.

In Fig. 3 of the drawing, a slightly different embodiment of theinvention is illustrated. In this instance, the neck of the container,while constructed in the manner above set forth in connection with Fig.2, is formed with screw threads as indicated at 23, and the skirt of thecap correspondingly threaded as at 24, so that the cover may be screwedinto position. It will be observed that the screw threads 23 are formedthrough the three thicknesses of material constituting the neck.

In this latter embodiment, the bottom construction of the container isalso somewhat different. Thus, the bottom wall 25 of the outer shell isformed with a peripheral flange united by means of a seam 26 with thelower end portion of the outer wall of the container.

It will be observed that I have provided a sheet metal container of avery practical character, especially adapted for use as a container forcreams, ointments and the like. Such a container is especiallyadvantageous as compared to the commonly used glass jars in that it islight in weight, which is a material advantage in the case of foreignshipments, and in that it is not subject to breakage either when thecontainer is accidentally dropped or when removing the cover. The sheetmetal construction furthermore lends itself readily to attractivedecoration in that the outer metallic surfaces may be readilylithographed, and moreover, because of the construction employed, thecontainer presents a neat and attractive appearance.
